ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 328,417, dated October 13, 1885.

Application filed March 13, 1885. Serial No. 158,652. (No model.)

To aZZ whom it may concern:

Be it known that I, JAMES LUOEY, of the city of Troy, county of Rensselaer, State of New York, have invented a new and useful Improvement in Roller-Skates, of which the following is a specification.

My invention relates to certain improvements in thatclass of skaterollers that are made with a groove or recess in revolution about the hub part of the rollers in the side faces of the latter, and which recesses or grooves are designed to catch the oil coming from the axlebearing, the object and purpose of my invention being to make such rollers better adapted for the uses designed.

My invention consists (as will be more fully detailed in connection with its illustration and in the claims) in the combination, with each of the skate-roller sides, of a projecting cheek formed therein, so as to project beyond the hub part of the rollers, an annular recess or gutter made in revolution in each of said projecting cheeks about the axle-bearing or hub part of the rollers, with the rim of said recess or gutter projected laterally beyond the hub part of the roller, radially-arranged grooves in the face of the hub part of the roller connecting the axle-bearing with the recess or gutter, and a cap adapted to attach to the rim of said recess, so as to cover the axle end and hub.

Accompanying this specification to form a part of it there is asheet of drawings containing two figures illustrating my invention, with the same designation of parts by letter reference used in both of them.

Of the illustrations, Figure lis aside elevation of a roller-skate, showing my invention applied thereto with the cap that covers the axle-head, and the recessed annular gutter being shown as detached from the roller and turned upon its side. Fig. 2 illustrates a diametrical section taken on the line ww of Fig.1.

The several parts of the skate and those of the roller containing my improvement are designated by letter reference, and the function of the parts is described as follows:

The letter T designates the sole or tread of the skate-body, and R the rollers, which are made with the side cheeks, A, and by which the rollers at each of their sides are extended out beyond the hub part of the rollers.

The letters a indicate axles, and p the axlepins.

The letters G indicate an annular recess or groove that is formed in the cheeks Aat each side of the rollers and in revolution about the hub, so that the inner rim of the said recess or groove extends beyond the end of the hub part ofthe roller, wherefrom the head of the axle is arranged to project.

The letters a indicate radially placed grooves made in the roller side faces about the axlebearing O at the outer end of the latter, and which grooves run from the bearing-opening to the gutter G, the purpose of these radial grooves being to direct any oil escaping from the bearing-opening into said gutter.

The letters 8 indicate slots oppositely made in the edges of the gutterG for theattachment of the cap O,and the latter is made with ears 6, having an L form, which, when the cap is applied, are passed in through the slots 8, and the cap is then turned, causing the ears on its under surface to engage with theinterior face of the outer wall of the annular chamber or gutter G, so as to hold the cap in place on the roller.

The letter F indicates a finger-piece on the outer face of the cap, by which the latter is turned to secure it in place.

I am wellawarethat skate-rollershavebeen made with an annular groove or recess formed in the side faces thereof; but they were not so made in projecting cheeks, which carried the rim of the recess out beyond the hub part of the roller to better catch the oil-drip from the hub part of the latter; neither were such annular gutters or grooves combined withacap that incloses both the head of the axle and hub.

I am also aware that a skateroller has been made with a groove in revolution to receive and secure a cap attached by nails; but I employ no groove to receive a cap where used by me, as the cap in my device fitsinto an opeuing formed by the inner rim of the gutter.

By arranging the cheeks A at the sides of the roller, so as to carry them out at the sides beyond the face of the axle-hub part of the roller to receive the annular gutter or groove, the inner rim of the gutter is (vertically considered) outside of the end of the axle-bearing, so that any grease escaping therefrom is better caught by the gutter than if the latter was made in the body of the wheel, and the inner rim of the gutter was vertically parallel with the end of the axle-bearing, as in the older devices of this kind.

Having thus described my invention, what I claim, and desire to secure by LettersPatent; 1s

1. In a skate-roller, the combination of the cheek A, formed in the roller side face, and the gutter or groove G, formed in revolution on said cheek about the axle-bearing with the inner rim of said gutter extending outwardly beyond the face of the hub part of the roller, substantially as and for the purposes set forth.

2. In a skate roller, the combination of the cheek A, made in the roller side face, the annular gutter or groove G, formed on said cheek in revolution about the axle-bearing of the roller with the outer face of the hub part of the roller vertically inside of the inner rim of the gutter, and the radial grooves N, made in the hub-face, said grooves connecting the axlebearing with the gutter, as and for the purposes set forth.

3. In a skate-roller, the combination of the cheek A,formed in the side face of the roller,

the annular gutter or groove G, having the March, 1885, and in the presence of the two,
